HTML, javascript - Displaying input value to a label
提问by user2362791
I want to display the value of an <input>
to a label or something like that, by using onkeyup so it's real time. But can only do it by using a second input instead of the label but I just want to display the value.
我想<input>
通过使用 onkeyup将 an 的值显示到标签或类似的东西上,以便它是实时的。但只能通过使用第二个输入而不是标签来做到这一点,但我只想显示该值。
This is my Javascript function:
这是我的 Javascript 函数:
function copyTo(obj) {
document.getElementById("utmatning").value = obj.value
}
And the HTML:
和 HTML:
<label>E-post:</label>
<input id="inmatning" type="text" onkeyup="copyTo(this)" placeholder="Skriv in e-post…">
<span>V?r ?terkoppling kommer att skickas till:</span>
<br>
<label id="utmatning"></label>

You can also call the keyup function of jquery and update the label on every keystroke: http://api.jquery.com/keyup/
您还可以调用 jquery 的 keyup 函数并在每次击键时更新标签:http: //api.jquery.com/keyup/

try this
试试这个
$( "#inmatning" ).keyup(function() {
$("#utmatning").text($("#inmatning").val());
});
Or
或者
$( "#inmatning" ).keyup(function() {
$("#utmatning").html($("#inmatning").val());
});
both should work
两者都应该工作

Try this also if you are seeking short method use jquery :
$( "#inmatning" ).keyup(function() {
$("#utmatning").text($(this).val());
});
or use
$( "#inmatning" ).keyup(function() {
$("#utmatning").text($("#inmatning").val());
});
but you are using function then you can also use:
function copyTo(that){
$("#utmatning").text($(that).val());
}
